To all whom'it may concern; Be it known that 1, WILLIAM F. MOUGHLER, a citizen of the United States, residing at T0- ledo, in the countyof Lucas and State of Ohio, have invented a new and useful Im- .provement in Sight-Glasses and Separators for Pneumatic Renovator s, of which the following is a specification.

My invention relates to a sight glass and separator for pneumatic dust renovators, and has for its object to provide a device of the kind that is adapted to be con led into the pipe connection to a suction too used for the extraction of dust from surfaces or material, whereby the dust laden air as it isdrawn through the connection is, by means of a vortex movement of the air produced in the glass, whirled around the inner peripheryoi the lass, and then drawn into the central-akis of hevortex and through the continuationof the connection, and thereby rendering the condition of the air passing through the tool more readily observable.

A further object is to provide a sight glass of the kind described with a hollow base, adapted to receive and retain the heavier particles of the dust carried by the air into the glass and thereby permit only the finer and more impalpable particles to be carried through the continuation of the connection.

In a rior application, Serial No. 295,547, I have s own my invention as connected into a dust removing, separating and collectin c aimed, and is now made the subject of this divisional a plication.

I accomp ish the objects of my invention hereinafter described, and illustrated in the drawings, in which Figure 1 is. a vertical longitudinal section of a sight glass constructed in accordance with my invention, and Fig. 2 is a similar view of a modified form of my invention showing a sight glass mounted on a hollow base, and adapted to' se arate and retain the heavier portions of the dust.

In the drawings 1 is a stand, preferably formed of a single casting, and comprising the base 2, the side trunnions 3, integral with the base, the circular top 4 integral with the standards, having the annular seat flange 5,

and the central tubular elbowinlet 6, preferably integral with the top 4; and extending oppositely and in line with the outer end portion 7 of the intake elbow 6. The outer endportion 11 of the outlet elbow 8 is also fitted to'be coupled to a suitable, pipe connection to the intake of the suction pump or other means of producing a vacuum.

On the top of the stand is mounted a lass cylinder 12 of a diameter to telescopical y fit into the seat flange 5, and to the top end of the cylinder is fitted a closure head 13, having an annular groove 14 of a diameter to receive the top end of the cylinder, and a flan e 15 concentric to the groove to telescopical y receive the cylinder. The top 4 is also provided with a periphery flange 16, perforated at intervals to receive the bolt rods 17 which extend downward to the top 4, of the stand, and have their lower end ortions threaded and run into threaded orifices in the top 4, and upon threaded top end portions of the rods are run the thumb nuts I8 by which the head 13 is closely compressed upon the top end of the cylinder 12.

Thus constructed, and having the outer end of the elbow' 6 coupled to the connection to the suction tool, and the outer end of the elbow 8 coupled to the connection to the suction pump, when the pump is operated, the air is exhausted from the glass cylinder, centrally in line with the opening to the elbow 8, forming a vacuum which produces a vortex movement of the air in the cylinder,

.similar to the vortex movement produced the inrush of air carries through the tool an i the connection to the stand, the dust that is in the path of the air, and the dust laden air, when it reaches the sight lass is whirled about the inner peritphery oft 1e glass by the vortex movement the air until it is finally drawn' into the axis of the vortex, and through the elbow 8 and its connection.

When used as a sight glass alone, as shown in Fi 1, all the dust is finally drawn through the e bow 8 and its connection. But, preferably, I use my sight glass in combination with a receiving base 19, in the modified form of my invention shown in Fig. 2,

. wherein there is substituted for the stand 1,

the base 19, comprising the cylinder 20, having a top closure 21, provided with the central cylindrical sight glass base 22, havin the flange 23 concentric to the top, an thickenin the wall 24 of the base "22, which is counter ored to telescopically receive flush with the inner wall ,the lower end of the sight glass cylinder 12,

The base 22 is provided with the tubular elbows 6" and 8, the outer end ortions of which are preferably integral wit 1 the base 25 22, at op osite diametric points of the base 22 the e ow 8. having an upper end por tion 9 concentric to the large upper end portion 7" of the .elbow 6", and curved down-' ward through the elbow 6, and the wall of the base 22 is provided with outer enlargements or bosses 25, opposite'the outer ends of the elbows, which are bored and ebunterboied and internally threaded for coupling thereto res ectively the connection 26 to the suction.

too and the connection 27 to the suction ump or other means of producing a vacuum. he sight glass 12 is provided with a top closure 13, constructed as shown in Fig. 1,

and-secured by the rods 17 to the flange, 23 of the base 22. When the sight glass is thus mounted on a receiving base and connected as aforesaid, the centrifugal movement of the air in the glass throws the heavier-particles of the dust drawn-in with the air outward beyond the upward moving current through theelbow 6*, and the indrawing influence of the vortex created by the elbow 8", and by reason thereof, and its greater weight, the heavier dust descends into the base cylinder 20, where it is retained and from -which it may be removed as required by means of the door 28, closing a suitable opening formed in the side of the base.

What I claim to be new is? a 1. In a sight glass for pneumatic renovators, a transparent cylinder having closed ends,'-a tube extending centrally into one end of the cylinder, and forming an inlet for the cylinder, a tube extending from the same end of the cylinder, and formmg an outlet for the cylinder, the outlet tube having its inner end portion concentric to the inner end portion of the inlet tube, the outer end portions of the inlet and outlet tubes being adapted to be connected into and'as parts of the passage for the transmission of air currents induced by a vacuum.-

2. In a sight glass and separator for pneumatic renovators, the combination of a glass cylinder, a sup ort for the cylinder adapted to inclose the lbwer end of the cylinder, a closure for the top end of the cylinder, a tubular inlet for the cylinder extending up ward through the support axially into the lower end of the cylinder, and a tubular out let for the cylinder extendin downward through the supdaort from the lower end of the cylinder, an having an open inner end concentric to the open inner end of the tubular inlet, the outer end portions of the tubular inlet'and outlet being adapted for the connection of the inlet and outlet into and as a art of a pipe line used for transmission of net laden air currents induced by a vacuum, substantially as set forth.

3. In a. sight glass for neurnatic renovators, the combination wit 1 a stand top, of a glass cylinder mounted endwise on the stand top, a closure for the top end of the cylinder, a tubular inletto the cylinder ex tending through the stand to axial to the cylinder, and a tubular outlet rom the cylinder having its inner end concentric to the open inner end of the tubular inlet, the outer ends of the tubular inlet and outlet being adapted for the .connection of the inlet and out et into and as a part of a i e line used for the transmission of dust llidbnair currents induced by a vacuum.

In witness whereof, I'have hereunto signed my name in the presence of two subscribing witnesses, this 27th day of Februar 1907.
